Jeremy;
Someone has probably pointed out in a later post that – unless you have an older RAW WATER cooled engine – the water that passes through your sea strainer never sees the inside of your engine block. If you have a fresh water cooled engine (most Yanmars have an F in the model number) the antifreeze you put in the strainer protects the strainer, the heat exchanger, and the muffler. The engine already has antifreeze in it, just like your car.

Poured about 5L in until it came out the exhaust (I think). I do have concern though if the thermostat was routing it into the block. I did warm up the engine first for ~20min under load with hopes that the thermostat would route the water to the block. Based on what Markek is suggesting, I may not have used enough AF...

As Marek suggested, you need several bottles. Stay warm! Joel
